The warning comes following an investigation into the suspicious death of a man on Aug. 2. Quebec City police say they found two packages of drugs next to the victim’s body and that it is the first time they have seized the dangerous substance in the area.

Quebec public health was tipped off about an overdose possibly caused by the same drug, but it was not confirmed, according to police.

In a statement issued on Tuesday, authorities said the drug can lead to overdose and even death among those who consume it.
